In radiotherapy, rays are specifically targeted at the tumour region.
The irradiated skin may redden, as with sunburn. Slight overheating or swelling may also be noticeable. Dry skin, skin flaking and itching are usually later symptoms. Depending on the site of irradiation, the mucous membranes may also be affected (e.g. in the mouth, throat or anal region).
Make sure you systematically follow the radio-oncologist’s skin care recommendations. No cream should usually be applied to the irradiated skin for one hour before and after the radiotherapy.
It is important to take good care of the irradiated skin region during and for up to about 3 weeks after the radiotherapy. After the end of the radiotherapy, too, the irradiated skin region should be consistently protected from the sun, for example with clothing, a hat or a scarf.
Tell the treatment team about any pre-existing hypersensitivities of your skin.
